CPI Full Form, CPI Base Year, Released Year, Indian Retail Inflation, WPI Vs CPI

CPI Full Form stands for Consumer Price Index, a critical economic indicator that measures the average change in the prices of goods and services consumed by households over time. It is an essential tool for understanding inflation trends and the cost of living in a country. In India, Retail Inflation in India is measured by the Consumer Price Index, which serves as a barometer of the economy’s health and the effectiveness of fiscal and monetary policies.

CPI Full Form and Its Meaning

The CPI Full Form is Consumer Price Index, which is a macroeconomic indicator that measures the change in the general price level of goods and services purchased by households. It directly reflects retail inflation in India measured by changes in consumer spending patterns and prices. CPI’s meaning is therefore associated with inflation from a consumer’s point of view.

The CPI basket includes goods and services such as:

  • Food and beverages
  • Housing
  • Apparel
  • Medical care
  • Education
  • Transportation
  • Fuel and light

These categories are assigned specific weights based on household consumption patterns. The index compares the current prices of this basket with the CPI base year prices to determine inflation.

CPI Released By Whom?

The Consumer Price Index India released by the Ministry of Statistics and Programme Implementation (MoSPI) through its National Statistical Office (NSO). The CPI is released by MoSPI on the 12th of every month at 4:00 PM. This timing aligns with the closure of major financial markets in India to avoid volatility and ensure greater transparency.

How is CPI Calculated in India?

CPI is calculated using the Laspeyres formula, which compares the cost of a fixed basket of goods and services in the current period to the base year. The formula is:

CPI = (Cost of Basket in Current Year / Cost of Basket in Base Year) × 100

The items in the CPI basket are categorised and assigned weights. The CPI base year is currently 2012, updated from 2010. The price data is collected from 1181 village markets and 1114 urban markets spread across 310 towns/cities.

The CPI base year is the reference year against which current price levels are compared. In India, the base year was updated from 2010 to 2012 and is used as the benchmark for all CPI computations since January 2015. The Central Statistics Office (CSO), under the Ministry of Statistics and Programme Implementation (MoSPI), is responsible for managing the base year and updating it periodically.

Purpose and Importance of CPI

CPI serves several important roles:

  • Inflation Measurement: CPI is a measure of retail inflation in India, helping policymakers gauge the rate at which prices rise.
  • Monetary Policy: The Reserve Bank of India (RBI) uses CPI data to design and implement monetary policy, including setting repo rates.
  • Wage Indexation: Dearness Allowances (DA) for employees are adjusted based on CPI.
  • Deflator in GDP Calculations: CPI is used to convert nominal GDP to real GDP, isolating the effect of inflation.

CPI Components and Weights

The CPI basket contains 299 items, which are broadly divided into:

  • Food & Beverages
  • Clothing & Footwear
  • Housing
  • Fuel & Light
  • Miscellaneous (Health, Education, Communication, etc.)

Each category has a specific weight, and price changes are monitored monthly.

Variants of CPI in India

India publishes four main variants of CPI:

  1. CPI (Combined) – For both urban and rural sectors (headline inflation)
  2. CPI (Urban) – Focuses on urban consumer prices
  3. CPI (Rural) – Focuses on rural consumer prices
  4. CPI-IW, CPI-AL, CPI-RL – For specific demographics such as Industrial Workers, Agricultural Labourers, and Rural Labourers

CPI and the Role of RBI

The RBI uses CPI as the primary metric to manage inflation under the inflation targeting framework adopted in 2016. The central bank aims to keep inflation within a target band of 4% ±2%. The Monetary Policy Committee (MPC) considers CPI data when deciding repo rates.

For instance, a rise in CPI indicates increasing inflation, prompting the RBI to raise repo rates to control the money supply. Conversely, a fall in CPI could lead the RBI to lower rates to stimulate economic growth.

Retail Inflation in India Measured By CPI

Retail inflation in India has shown considerable improvement. As of FY 2024–25, retail inflation fell to 4.6%, the lowest since 2018–19. The year-on-year CPI inflation for March 2025 dropped to 3.34%, marking the lowest since August 2019. This moderation is attributed to:

  • Strategic buffer stock releases
  • GST reductions on essentials
  • Targeted subsidies under schemes like PM Ujjwala Yojana

CPI vs WPI Key Differences

To understand the full scope of inflation measurement in India, it’s important to differentiate between the two main indices used—CPI and WPI. While both aim to capture price movement, their approach, components, and policy relevance vary significantly.

CPI vs WPI Key Differences
Aspect Consumer Price Index (CPI) Wholesale Price Index (WPI)
Full Form Consumer Price Index Wholesale Price Index
Focus Area Retail price to consumers Wholesale prices at the bulk level
Covers Both goods and services Only goods
Calculated By NSO under MoSPI Office of the Economic Advisor, Ministry of Commerce
Base Year 2012 (for CPI) 2011–12
Items Tracked 448 (rural) + 460 (urban) 697 items
Frequency Monthly Weekly for primary/fuel, monthly for others
Relevance Reflects consumer cost of living Tracks business input cost trends
Inflation Stage Final stage (consumer level) Early stage (production level)

Recent CPI Trends in India (2024–25)

India’s inflationary trends, as captured by the CPI, have undergone notable changes in recent years. The fiscal year 2024–25 reflects a steady moderation in retail inflation, showcasing the impact of macroeconomic stability measures and monetary policy.

  • Retail inflation dipped to 4.6% in FY 2024–25, the lowest since 2018–19.
  • March 2025 headline CPI was 3.34%, down from 3.61% in February.
  • Food Inflation declined to 2.69% (lowest since 2021).
  • Urban CPI slightly rose to 3.43%, while rural CPI fell to 3.25%.
  • Fuel & Light inflation rebounded to 1.48% in March 2025.
  • Items with the highest inflation: Coconut oil, gold, silver.
  • Items with the lowest inflation: Ginger, tomato, cauliflower.

Government Interventions to Control CPI

The government has played a proactive role in stabilising CPI-driven inflation through strategic policies and market interventions. These efforts are targeted at ensuring affordability for the masses while maintaining the momentum of economic growth.

The Government of India has implemented several measures to moderate CPI levels:

  • Maintaining buffer stocks of essential commodities
  • Subsidised sales of rice, wheat, and pulses
  • Reduced GST on essentials
  • Strategic imports and export controls

These efforts have successfully curbed retail inflation, improving affordability and supporting economic growth.
